On the origin of magnetosheath plasmoids and their relation to magnetosheath jets [PDF]
Journal of Geophysical Research: Space Physics, 2015 AbstractWe investigate localized magnetosheath and solar wind density enhancements, associated with clear magnetic field changes, and therefore referred to as magnetosheath/solar wind plasmoids, respectively. Using Cluster data, we show that there are two distinct populations of magnetosheath plasmoids, one associated with a decrease of magnetic field ...

The characteristics of lion roars, which are intense packets of electromagnetic waves characteristically found in the magnetosheath, are studied. The average frequency of the emissions is 120 Hz, with over 90% occurring between 90 and 160 Hz (which is near one-half the local electron gyrofrequency); over 70% of all emissions last a mere 2 sec or less ...

Magnetosheath study: INTERBALL observation
Advances in Space Research, 2000Abstract The fundamental question of the solar wind magnetosphere coupling is how the solar wind and IMF are modified before they hit the magnetopause. Various models have been proposed to describe the magnetosheath flow but none of them includes the presence of the foreshock region.

Magnetic fields of the magnetosheath
Reviews of Geophysics, 1976The magnetic field of the magnetosheath is most naturally discussed in terms of its steady state and its fluctuating components. The theory of the steady state field is quite well developed, and its essential features have been confirmed by observations.

The cusp-magnetosheath interface
Journal of Geophysical Research, 1976Three Heos 2 passes through the distant cusp-magnetosheath transition in summer 1973 are described. By combining data from three different experiments on board Heos 2 it has been possible to identify a distinct transition from a ‘stagnant’ plasma (the distant cusp) to a region of ‘reduced flow’ magnetosheath.

Magnetosheath whistler turbulence
Journal of Geophysical Research: Space Physics, 1985Magnetic field short‐period fluctuations δB are observed throughout the earth's magnetosheath. We report a study of these fluctuations with frequencies 20 < f < 1000 Hz in which the turbulence has a broadband spectrum δB²(f) varying approximately as f−α, where α ∼ 4±0.5, or consists of a narrowband intermediate frequency peak superimposed on the ...

Abstract This paper describes an approach to a theoretical interpretation of Interball-1 satellite measurements data in two cases of the satellite’s crossings of the magnetosheath. An interpretation is made of both the measured crossings of the magnetosheath boundaries and the behavior of the registered plasma parameters. In our case, it is the value

Magnetosheath electrostatic turbulence
Journal of Geophysical Research: Space Physics, 1979By using measurements with the University of Iowa plasma wave experiment on the Imp 6 satellite a study has been conducted of the spectrum of electrostatic plasma waves in the terrestrial magnetosheath. Electrostatic plasma wave turbulence is almost continuously present throughout the magnetosheath with broadband (20 Hz to 70 kHz) rms field intensities

Abstract We report a testing of the earlier developed in the Institute of Mechanics of the Bulgarian Academy of Sciences numerical data-based 3D model of the system magnetosphere–magnetosheath with real satellite data. The model is a result of a self-consistent solution of two tasks: (i) Chapman–Ferraro problem for an arbitrary 3D magnetopause with ...
